Customizing XML generation in Rails -

i new rails , have written few models. 1 of xml generated model looks this:

<book>     <read type="boolean">true</read>     <title>julius caesar</title>     <id type="integer">1</id> </book> 

the serialized xml want have more control on it. want generate same in different format. like:

<book read="true" id="1">     <title>julius caesar</title> </book> 

how achieve this? have done research , found to_xml method should overridden. not sure how it.

you can use custom ::builder::xmlmarkup this. however, the documentation active record serialization (see last code example) buggy. can this:

class book < activerecord::base   def to_xml(options = {})     # load builder of not loaded yet     require 'builder' unless defined? ::builder      # set indent 2 spaces     options[:indent] ||= 2      # initialize builder     xml = options[:builder] ||= ::builder::xmlmarkup.new(:indent => options[:indent])      # real action starts     xml.book :read => read, :id => id       xml.title self.title     end   end end
